Phase B: AI press-release rewrite pipeline

Pluggable rewrite client (Anthropic default, ollama/openrouter stubs)
using claude-opus-4-7 with prompt caching on system prompt + style guide.
Routes the raw submission through:
  1. bb.ai_original_submissions  — raw never edited
  2. bb.ai_rewrite_jobs          — every attempt logged with token counts
  3. quality gates               — AI-tell banned-word check + heuristic
                                   AI-detector score (threshold 0.65)
  4. regenerate up to 3x         — on banned words or detector trip
  5. bb.ai_rewritten_articles    — status ai_rewritten_pending_review
  6. /admin/review-queue          — list + detail page with approve / reject /
                                   needs-human actions; on approve, the
                                   original submission is FK-linked to the
                                   published rewrite

New files only — no existing routes or contributor flow modified.
Persona auto-selection routes by beat keywords; 6 personas seeded
(marcus-halverson, elena-vasquez, darren-okafor, sarah-quinn, mike-trayton,
priya-rao) with SVG monogram avatars in public/assets/images/personas/.

Smoke test (Matrox / ST 2110 sample press release):
- persona auto-routed to darren-okafor (protocols-specs)
- anthropic 22.3s, in=2616 / out=1372 tokens
- gates passed first try, score=0.000, no banned words
- review_queue row created
